LIQUID FUEL.

No Drawing. Application filed June 9, 1922, Serial No. 567,170, and in Argentina January 18, 1922.

This invention relates to an improved liquid fuel, particularly suitable for being transformed into motive power by means of any of the known systems of internal combustion engines, being also specially adapt-ed for heating, lighting and other industrial purposes.

The primary material or liquid which forms. the base of the novel liquid fuel, for reasons of economy, is obtained from the fermentation of the residues resulting from the elaboration of sugar cane, such molasses, as Well as of those obtained from the sugar beet, potatoes, manioc, grain (damaged or not), out stalks, plantains, grapes and other fruit, etc.

l-leretofore, the direct use of the raw fermentation products containing all of their distillable alcoholic components for industrialpurposes of any description has not been practiced.

The industrial use of the aforementioned waste products, for the purpose set forth, may be considered as'quite unique, up to this date, and permits of obtaining most important advantages as regards the ob tention of the first fuel of this kind, suitable for use.

The new liquid fuel offers the particular condition that it distils at temperatures ranging from d0 C. upwards, and that it may be fractioned as required by the particular use to which it is destined and that said products differ from each other, as to the physical properties, in accordance with the requirements of the different uses above referred to.

It will. also be apparent that for each particular use, preferably one particular form or identification of the fuel, distilled at a given temperature, should be employed, of similar chemical composition; this allows of accordingly increasing the useful output,

as the amounts of the hydro-carbon, bodies consumed in each of said distillations, are entirely constant in apparatus of different yields.

The fuel compound in accordance with this invention is obtained by the following reactions:

1. The result of any alcoholic fermentation, either grouped or separate or subgroups of same (alcohols up to the poly valents, saturated or not, in a similar manner and of the same composition as the con comitant secondary products, aldehydic,

lretonic, etc), obtained by different actions from any material containingcarbohydrates, sugar, starch, cellulose, convertedby suitable forming processes is distilled to obtain a distillate containing about 90% combustible. its 1 have already stated above, the essential feature of this invention consists in making use of thefermentation caused in vegetable waste products or in byproducts, even though the same should. have been damaged or frozen. 7

2. l l ith varying proportions of paraformaldehyde (C11 0), and of metafornr aldehyde (CH OO according to the richness of the fermentations obtained by the above distillation.

3. With varying proportions, similarly, of fractions of mineral oils distilling from density 0.635 to density 0.86s; according to the use to which the fuel is to be applied.

4-. With proportions, also varying, for similar reasons, of the products of dry distillation of wood, from density 0.792to density 1.056. r

The process is initiated by starting with any dilution of the product of the fermented material, for instance, (a) must, or (5) phlegms; alcohol; head or tail products ob tained in the rectifying processes for the separation of ethylicalcohol, etc; or (0) products of a suitable pyrog enous distillation of any vegetable materials or of certain animal products. The distillate or product shall contain about 90% combustible hydrocarbon compounds resulting from fermentation.

Said liquid or fluid fuel is directly obtained, even though the raw material a, 7) has not been submitted to any preliminary distillation. for the purposes of concentration, with the addition of the products 2, 3 and 4t, the said several ingredients being suitably submitted to maceration during a period of i8 hours, even in the case of the concentrated product of the total fermentations having been diluted in ninety per cent of water.

If the raw material is that of the type a, it will be sufficient to cause the direct reaction of the fermented products obtained with the ingredients 2, 3 and i, the resultant products being separated by fractional distillation at every half degree, according to the use to which they may be destined; this constitutes a particular feature of their obtention, not known heretofore; the said pouring otl', treatment in a centril'inzal mil suitable mixing machines provided with agitators, etc; according to the most economic source of motive power obtainable in the locality Where the process is to he carried out.

The resulting product not only'possesses the total percentage combustible fermented carbo-hydrates of an entirely different molecular structure, but the same may also he delivered for conrnni'iption with a Varying additional percentageot 20% or more of distillation Water or of Water added thereto. according to the conditions of the raw material a, b, a, used in transformation.

Among the advantages which otters the adoption of this productforthe production of motive power it may he mentioned that 90% of its composition consists of distillates offermented Carlie-hydrates of the raw materials; a complete absence of s1nol e; no c-orrosions are caused in the engine. nor is its operation obstructed by incrustations of carbon; no excessive orerheatuig is caused by its combustion, etc.

A mass containing at least ten percent of:

on H W :3. in? O; :n. 770

Total 99. on?

Having nor-r described my said invention, I declare that What I claim as new and de sire to secure by Letters Patent. is?- The method of making" a liquid fuel which comprises mixing: a mash containing ahout ten percent fermented distillahle products,. filtering the same. adding" a distillalile (an hnrating n'iaterial to produce a density aliore seren tenths and then adding; methyl alcohol containing about twenty lire percent acetone to produce a distillate llfl'Vlll 'l a density tl lfllli seventy-ought l'iundredths.

In testimony that I claim the foregoing as my invention, I have signed my name.
